Troubles cross building X11

[Thomas Jourdan-2]

Hi

I am cross-building a generic i486 target. My host is ubuntu 9.04 (64
bits). The build fails on X11 stuffs, like libxcb, libx11 packages...

I tracked a little the problem and the configure stage of some packages
test for the presence of files. For example :
- libxcb tests for /usr/X11R7/share/xcb/xproto.xml
- libx11 tests for /usr/X11R7/include/X11/keysymdef.h

Those files are provided by xproto, and are present in the $root
directory but the configure scripts tests paths which point to host
files. I didn't find a way to tell the configure script an alternative
path.

Shouldn't a wrapper handle this and add the $root directory as a
prefix ? Isn't is automatic ? How can I add such a wrapper ?

Regards,
Thomas

I digged a little around libxcb-1.4, which is the first X related
package which fails.

In the configure script, line 12791, the script looks for the
xcbincludedir :

# Find the xcb-proto protocol descriptions
{ $as_echo "$as_me:$LINENO: checking XCBPROTO_XCBINCLUDEDIR" >&5
$as_echo_n "checking XCBPROTO_XCBINCLUDEDIR... " >&6; }
XCBPROTO_XCBINCLUDEDIR=`$PKG_CONFIG --variable=xcbincludedir xcb-proto`
{ $as_echo "$as_me:$LINENO: result: $XCBPROTO_XCBINCLUDEDIR" >&5
$as_echo "$XCBPROTO_XCBINCLUDEDIR" >&6; }

and the result is /usr/X11R7/share/xcb

Then in the src/Makefile, the first action is to create symlinks to xml
file and then run a python script :

ln -s -f /usr/X11R7/share/xcb/xproto.xml xproto.xml
/usr/bin/python ./c_client.py
-p /usr/X11R7/lib/python2.6/site-packages /usr/X11R7/share/xcb/xproto.xml

The problem is that the link should point to
$root/usr/X11R7/share/xcb/xproto.xml and the python script should use
this file.

What is the best way to change XCBPROTO_XCBINCLUDEDIR ? A patch to the
configure file ?

Thomas

I just found how to solve : easy !

I attached a conf file for libxcb to cross build.
